Has anyone had any luck keeping the plastic shields around the waterjet clean?  I have tried rain-x and just hoseing them off but they never stay clean for more than a day.  Only reason i as is customers like to come see the waterjet at work.  The dirty shiedls just make the machine look bad.  Thanks for any advice.

We've got the same issue.  They normally aren't hard to clean.  The dirt seems to just need the surface tention broken to wash off, but it is a pain to we tthem down and then lightly rub them with a shop towel or something.  I was going to try rain-x but I guess I can save my time.
